[parisc-linux] CONFIG_SYSCTL is not set

[parisc-linux] CONFIG_SYSCTL is not set

[Grant Grundler]

Hi folks,

By default, CONFIG_SYSCTL is not set.
And I get the following errors when linking:

fs/fs.o: In function `nfs_put_inode':
fs/fs.o(.text+0x399dc): undefined reference to `nfs_debug'
fs/fs.o: In function `L1261':
fs/fs.o(.text.init+0x18fc): undefined reference to `nfs_debug'
net/network.a(sunrpc.o): In function `rpc_create_client':
sunrpc.o(.text+0x360): undefined reference to `rpc_debug'

All of these errors are a result of not having globals defined in
net/sunrpc/sysctl.c.  sysctl.o only gets built when CONFIG_SYSCTL=y.


With CONFIG_SYSCTL=y, I get a different linker error
kernel/kernel.o(.data+0x3b4c): undefined reference to `sysrq_enabled'

(which willy already pointed out...See
http://puffin.external.hp.com/mailing-lists/parisc-linux/2000/05-May/0103.html)

This is very reproducible (going back and forth) in my build tree.
I don't see how willy got around it.

Do we want the build to work with or without CONFIG_SYSCTL?

If anyone wants to build x86 install/rescue disks, I think they can't now.
Either the Configure.help is wrong or the code is wrong.
I don't know how to submit a BUG.
Any pointers on where this bug should go?

thanks,

Hi Grant,

You probably already worked this out, but mine builds fine with

CONFIG_SYSCTL=y
# CONFIG_MAGIC_SYSRQ is not set

As a temporary hack, I changed arch/parisc/defconfig to enable
CONFIG_SYSCTL and defined sysrq_enabled in arch/parisc/kernel/setup.c.
The kernel will link this way at least, but it's not the "right answer".

You were right.  It's just annoying behaviour not to compile at all, so
I submitted a patch to Alan (obviously, RPC_DEBUG doesn't make sense if
CONFIG_SYSCTL isn't defined).

So ac7 shouldn't have this problem.
